, Application filed February invention relates to diagnostic reflec i tors worn on thehead byoptioians', physiclans and the li for use in the illumination ofthe eye's throat, etc a In the presentuse of such reflectors, par- 1 ticularly in diagnosing throat affections, it

is highly desirable'that the wearer of the reflector be protected against the cough ng of a patient. It is therefore, a purpose. of my invention to provide an attachmentfor such reflectors which. operates to effectively shield the nose and mouth ofthe wearer. I

It is alsoa purpose .of niy in'vention to provide a rnouth andnoseshieldcapable of being associated with afhead reflector n a. Inannerfto allow of an adjustmentthereof "with respect to the nose and mouth ofthe wearer} to permit of its movement to and retention in a non-shielding position when the shield is not'in use; and the mounting f thereof on. the headband of therefiector so v as to present alsmo oth andhuninterrupted surface to the inner sideof the band onto the head ofthewearer I'Wmdescribe 0111. .Q QifOrm of nQ at d mouthshield embodying my invention and Q its adaptation to a conventional form fo't "diagnosticreflector and will then polnt out the novel features thereof in claims. f

A-locking Washer 32 is adapted to be interposed between the ball head 18 and the plate 31,'as clearly-shown in Figure 2, and this washer is provided with a s'lot'in which the'shank17 is received. The washer is designed to occupy the space between the head 18 and the plate 31 and when applied funetions'to aflex the platev inwardly, thus placing the plate under tension andithereby exerting suflicient pressure upon 'thetongues to cause the latter to bindingly retain the extensions 27 [against accidental movement, so that any vertical T,adjustment of the extensions :can be maintained.
